Changing data doesn't cause select2 to update

[CWSites]

I'm trying to change All to the text of whatever basisList is selected. I am able to correctly update it to Users (ID) using componentWillMount().

My problem is, if I change the basisList that is selected to machines which calls this.updateResolutionText() does not cause select2 to re-render. I can see that my state has been updated correctly, however select2 isn't updating.

What am I missing? I would think that by updating this.state.resolutionOptions that my select2 component would automatically update, thus displaying the new text.

this.state = {
	resolutionOptions: [
		{ text: 'All', id: 0, value: 'all' },
		{ text: 'Month', id: 1, value: 'Monthly' },
		{ text: 'Day', id: 2, value: 'day' },
		{ text: 'Day-Hour', id: 3, value: 'Day-Hour' },
		{ text: 'Hourly (0-23)', id: 4, value: 'hourly' },
		{ text: 'Day of Week', id: 5, value: 'dow' }
	]
}

componentWillMount() {
	this.updateResolutionText()
}

componentDidUpdate() {
	// this returns correctly {text: 'Machines', id: 0, value: 'all'}
	console.log(this.state.resolutionOptions[0]);
}

updateResolutionText() {
	let basisList = [
		{text: 'Users (ID)', id: 0, value: 'users'},
		{text: 'Machines', id: 1, value: 'machines'}
	];
	let options = [...this.state.resolutionOptions];
	let comparison = 'users';

	if(basisList) {
		for(let i = 0; i < basisList.length; i++) {
			if(basisList[i].value === comparison) {
				options[0].text = basisList[i].text
				break;
			}
		}
	}

	this.setState({ resolutionOptions: options });
}

<Select2 className="form-control"
		 ref="resolution"
		 data={this.state.resolutionOptions}
		 defaultValue={0}/>
